'vec_en' is set when interrupt vectors are detected and associated event fds are set. Those event fds are stored in efds[]. 'intr_vec' is reserved for device driver to initialize the vector mapping table. When the event fds add to a specified epoll instance, 'eptrs' will hold the rte_epoll_event object pointer. Signed-off-by: Danny Zhou Signed-off-by: Cunming Liang --- v7 changes: - add eptrs[], it's used to store the register rte_epoll_event instances. - add vec_en, to log the vector capability status. v6 changes: - add mapping table between irq vector number and queue id. v5 changes: - Create this new patch file for changed struct rte_intr_handle that other patches depend on, to avoid breaking git bisect. lib/librte_eal/linuxapp/eal/include/exec-env/rte_interrupts.h | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/lib/librte_eal/linuxapp/eal/include/exec-env/rte_interrupts.h b/lib/librte_eal/linuxapp/eal/include/exec-env/rte_interrupts.h index bdeb3fc..9c86a15 100644 --- a/lib/librte_eal/linuxapp/eal/include/exec-env/rte_interrupts.h +++ b/lib/librte_eal/linuxapp/eal/include/exec-env/rte_interrupts.h @@ -38,6 +38,8 @@ #ifndef _RTE_LINUXAPP_INTERRUPTS_H_ #define _RTE_LINUXAPP_INTERRUPTS_H_ +#define RTE_MAX_RXTX_INTR_VEC_ID 32 + enum rte_intr_handle_type { RTE_INTR_HANDLE_UNKNOWN = 0, RTE_INTR_HANDLE_UIO, /**< uio device handle */ @@ -49,6 +51,8 @@ enum rte_intr_handle_type { RTE_INTR_HANDLE_MAX }; +struct rte_epoll_event; + /** Handle for interrupts. */ struct rte_intr_handle { union { @@ -58,6 +62,12 @@ struct rte_intr_handle { }; int fd; /**< interrupt event file descriptor */ enum rte_intr_handle_type type; /**< handle type */ + uint32_t max_intr; /**< max interrupt requested */ + uint32_t nb_efd; /**< number of available efds */ + int efds[RTE_MAX_RXTX_INTR_VEC_ID]; /**< intr vectors/efds mapping */ + struct rte_epoll_event *elist[RTE_MAX_RXTX_INTR_VEC_ID]; + /**< intr vector epoll event ptr */ + int *intr_vec; /**< intr vector number array */ }; #endif /* _RTE_LINUXAPP_INTERRUPTS_H_ */ -- 1.8.1.4
